Answer:
Winnowing is an agricultural method developed by ancient cultures for separating grain from chaff. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation.
Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. ... Sieves are also used to separate stones from sand.
Threshing is the process of loosening the edible part of grain from the straw to which it is attached. It is the step in grain preparation after reaping. Threshing does not remove the bran from the grain. Threshing may be done by beating the grain using a flail on a threshing floor
Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism
Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. ... An incomplete separation is witnessed during the separation of two immiscible liquids.
